Suitable for wide voltage use
The motor design takes into account the voltage changes in different regions, making the motor suitable for use in multiple regions and ensuring user performance.
Improve the insulation level and increase the service life of the motor
The standard motor adopts an F-class insulation structure, which improves the service life of the motor and increases the reliability of the motor.
high efficiency
The motor adopts an optimized design, has high efficiency, and can produce considerable energy-saving effects.
3. Reasonable structural design
Flexible pinout direction
The motor junction box can be installed on the top, left or right side of the motor. The junction box itself can be rotated and installed. The junction box of the 71-132 base can be rotated in 4*90 directions. The junction box of base 160 and above can be rotated in 2*180 directions. Users must indicate the direction of the junction box and outlet holes when ordering.
Beautiful motor shape
The heat dissipation ribs of the machine base are designed to be distributed vertically and horizontally. The end caps, junction boxes, and air hoods are all newly designed, with a unique and beautiful appearance.
